WEATHER-STRIP.

SPECIFICATIQN forming part of Letters Patent No. 349,787, datedSeptember 28, 1886,

Application filed June 26, 1886. Serial No. 206,355.-

To all whom it may concern.-

Beitkuown that I, JOHN W. FARR, a citizen of the United States,residingat Marion, in the county of Grant and State of Indiana, haveinvented a new and useful Improvement in Weather-Strips, of which thefollowing is a specification.

My invention relates to an improvement in weather-strips for doors; andit consists in the peculiar construction and combination of devices,that will be more fully set forth hereinafter, and particularly pointedout in the claims.

In the drawings, Figure 1 is a perspective view of a portion of a doorand door-frame provided with a weather-strip embodying my Fig. 2 is avertical sectional Fig. 3 is a detail reverse anism.. Fig. at is aperspective View of a portion of a weather-strip.

A represents the door-frame, the sill of which is provided with theusual thresholdstrip, B.

0 represents the door, which has one edge hinged in one side of thedoor-frame in the usual manner. The bottom edge of the door is cut awayon one side, thereby forming a recess, D, in which is located themetallic weather-strip E, which extends entirely across the bottom edgeof the door, and has its outer edge. turned downwardly, and therebyforming the lip e. The said weather-strip at its inner edge is providedat its extremities with projecting trunnions e, which are journaled inthe lower edges of metallic plates F, that are secured in countersunkrecesses in the edges of the-door, at the lower side of the same,

by means of screws. The inner edge of the strip beyond the pivot-pointis turned upward, as at m, and fits in a channel, b, out out of the doorat the end of recess D. From this construction it will be readilyunderstood that when the door closes the weather strip is adapted todrop,so as to cause the lip e to bear upon the inclined outer side ofthe strip B, and thereby entirely close the crack at the lower edgeofthe door.

H represents an inclosing-case, which is secured on the outer side ofthe door,near the outer edge of the same, by means of screws I.

The said case is provided at its edges with an (No model.)

inwardly-extending flange, h, and formed with the side flanges of thesaid case are the inwardly-extending ears h, which project into ahorizontal recess which is made in the outer side of the door. Avertical opening, K, is made in the case H, at the outer edge of thesame, and near its lower end.

L represents a rock-shaft, the ends of which are j on rnaled in openingsin the ears h. From the said rock-shaft, at one end of the same,

' projects a tappet-arrn,L,the outer end of which is curved downwardly,andpasses through the slot K and projects from the outer side of thecase. At the opposite end of the said rock-shaft is an arm, L". Aconnecting-rod, M, has its upper end attached to the said arm, and thelower end of the said connecting-rod is attached to the weather-strip E.

N represents a coiled spring which is placed on the shaft'L. One end ofthe said spring is attached to the said shaft, and the other end of thespring bears against the inner side of the case II. The function of thisspring is to turn the rocl -shaft so as to cause the tappetarm L tonormally project from the face of the case H, and also to raise the armI and thereby normally raise the weather-strip.

0 represents a casting or frame which is secured to the inner side ofthe door-frame at the edge against which the door closes. At theprojecting end of the said case-of the said casting or frame isjournaled a roller, P.

The operation of my invention is as follows: When the door is closed,the tappet-arm L strikes againstthe roller 1?,and is thereby depressed,causing the shaft L to partly rotate, and thus lower the outer end ofthe arm L and thereby lower the free edgeor lip e of the metallicweather-strip, so as to cause the latter to bear upon the upper inclinedouter side of the door-strip B, and thus effectually close the crack atthe bottom of the door. As soon as the door is opened the tappet arm Lisdisengaged from the roller 1?, thereby causing the spring N to reversethe movement of the rock-shaft and raise the lip e of the weatherstrip,so as to enable the latter to clear the door-strip B. p

As the rod M is connected to the weatherstrip in advance' of thepivot-point, it will be I seen that the forcing of rod M downward causesthe inner edge of the strip to work up ward, with the lip m fitting inthe channel Z). This lip thus serves to limit the movement of the strip,and also to exclude drippings from the door from obtaining access to theroom, as will be readily understood.

Having thus described my invention, I claim- 1. The case H, adapted tobe secured to the door, and having the slot K, in combination with thehorizontal rock-shaft L, journaled within the case, the tappet-arm L atone end 3. In combination with the strip E, pivoted to the lower edge ofthe door, and having the lip m on its inner edge fitting within a recessof the door, the rod M, connected to the strip in advance of thepivot-point, and operating means for the rod M, whereby when the latteris operated the front end of the strip is forced down and the lip m isthrown up into the recess of the door, said lip limiting the downwardmovement of the strip, and also serving to exclude drippings from thedoor, as set forth. Y

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.

JOHN w. FARR.
